Getting realtime metric values with the .NET SDK

Wed, 04 Mar 2009 17:59:09 Z

In powershell, I can do:

Add-PSSnapin microsoft.hpc
get-hpcmetricvalue -Scheduler <myCluster'sName>

And I get all of the realtime CPU/Network/Disk usage from each node in the cluster.

How can I get this info through the .NET SDK ?

Thanks.

You can run those cmdlets with correct pipleline to filter our the desired value in your C# code.

1. the CPU/Network/Disk usage you get with "get-hpcmetricvalue" are not realtime, the default interval for each metric is "1min". you can export-hpcmetric to see the interval setting for one metric, change the interval in exported xml file, then change this setting with import-hpcmetric command. however, the minimun interval is 1min, you cannot set this to a value less than 1min.
2. if you are an cluster admin, you can query realtime perfmance counter values with .NET api. pls. refer to http://msdn.microsoft.com/en-us/library/system.diagnostics.performancecountermanager.performancecountermanager(vs.80).aspx for more information.

Errr, one correction: Get-HpcMetricValue IS realtime. And what's more Get-HpcMetricValue accepts NodeName, (Metric's) Name and Counter (perf counter instance name) as parameters, so you can get perf counter value for specific node and/or perf counter instance.
